CEMENTING APPARATUS.

- SPECIFICATION forming part of Letters Patent No. 626,185, dated May 30, 1899.

Application filed January 28, 1897. Renewed July 15, 1898. Serial No. 686,037. (No model.)

To all whom it may concern: I

Be it known that I, ALONZO B. MoOoY, a citizen of the United States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Oementing Apparatus for Shoe -Vamps and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention is for applying cement to the skived edges of Vamps, uppers, and other parts of shoes requiring cementing.

It consists in an upright closed-top cementtank, to the bottom of which is removably attached a cement gravity-pipe provided with a cock for controlling the cement-supply to a cement-seat raised on the gravity-pipe and chamfered or reduced at its top to form a narrow vamp-support, and thus prevent the cement from running over other than the vamp skived edge or part to be covered with cement. A tilting jaw,pivoted on the top of the gravitypipe and working under yielding pressure, has a cement-chamber above the fixed cementchamber of the gravity-pipe, which receives its cement through said fixed chamber and one and the same gravity-pipe.

On reference to the accompanying sheet of drawings, making part of this specification, Figure 1 is a side elevation of a cementing apparatus embodying my invention. Fig. 2

is a vertical and longitudinal section of the cement gravity-pipe and tilting jaw. Fig. 3 is a surface view of the plug-cock. Fig. 4 is a shortened view of the end of the cement gravity-pipe, showing the cement-seat raised above the gravity-pipe and chamfered or reduced at its top to form a narrow vamp-support,and thus prevent the cement from spreading over the part of the vamp not to be covered with it; and Fig. 5 is a plan view of the vamp-guide means.

Similar letters refer to similar parts in the several views.

A is a cement-tank having a suitable number of carrying-legs B. It is closed at the top,

skived edge of the vamp.

Gr, Figs. 2 and 3, is a plug-valve in the continuous valve-seat and cement-chamber F, having an axial opening 01, shown in full lines, Fig. 2, and is provided with a side entranceport 6, communicating the axial opening d with the gravity-pipe E for forming a gravity cement flow from the tank Ato the chamber F. A circumferential groove f is formed in said plug-valve G, into which extends the end of a pin 9, Fig. 2, projected through the pipe E for holding it from dropping out of its seat when operated through the medium of a leverhandle 71, Figs. 1 and 2. For limiting the :turning of the valve G the bottom 11 of the valve-seat F, against which the collar j turns, is partially cut away at It for the cock-lever h, which abuts the ends thereof in full opening and closing.

H is a cementing-jaw which is capable of a tilting motion on a transverse pin or pivot Z in bearings I on the gravity-pipe E. It has a cement-chamber J, Fig. 2, which has no independent cement gravity-pipe or supply-channel, but receives its cement by gravity through the cement-chamber F of the gravity-pipe E, above which it is located. At the mouth of .the cement-chamber J is formed an annular groove on for the reception of an annular absorbent pad K,whose openingn can be slightly smaller than the cement-chamber J to hold the cement from dropping out and to have it being cemented is regulated by a screw L, which engages an opening in the inner end of the tilting jaw II, and a spiral spring M, bearing endwise between the screw in its opening p and an opening q in the top of the pipe E,

whereby a yielding pressure is imparted to the cementing end of the jaw consequent upon the degree of pressure of the screw on the spring.

For closing and holding the tilting-jaw cement-chamber J and its absorbent pad K on the bottom or gravity-pipe cement-chamber F while filling said chamber J through said gravity-pipe chamber F and generally operating the tilting jaw a link-motion is employed, consisting in a hand-lever N, pivoted to the side of the gravity-pipe E, and a connecting-link O, pivoted between said lever N and the tilting jaw II, by which when the cock G is properly turned said tilting-jaw cementchamber J is supplied by gravity with cement from tank A through the only pipe or channel E into the cock G and cement-cha1nber F, and thence through the opening 91 in the an nular pad K into said chamber J, by which two vamps can be cemented at a time.

As shown, Figs. 1 to 5, the tank A is elevated and rests on legs 13, assisted by notches r in the feet .9, which engage the screws t on the holdingbench. The slots engage the screws or plugs and on the machine being turned a perfect hold is effected.

To fill the tank A with cement, the plugvalve G is closed and the screw-plug C and its petcoek D removed, by which the tank A and the gravity-pipe E are filled through the screw-opening of said screw-plug C.

It will be seen that there is no air left in the tank to dry up the cement, and should it be required it can be admitted through the petcock D and its screw-plug O. \Vhen the tilting jaw II is closed on the gravity-pipe vamp-seat F by the lever N, the valve G is turned so that there is communication from the tank A through the only supply-channel or gravity-pipe E into the cement-chamber F, and thence to the cement-chamber J of the tilting jaw II. loth chambers F J being supplied by gravity with cement through one and the same single channel or gravity-pipe E should the cement become dry and clogged, and thus interfere with the operation of the vamp-eementer, the hindrance can be removed by taking apart and heating the tank A, gravity-pipe E, valve G, and the tilting jaw II, which, being preferably of cast-iron, readily submit to heat without injury for burning out the dried cement.

The top edge of a shoe-vamp is covered with cement on its skived edge, which is turned over so as to be stuck together with the cement and subsequently stitched for finish and elfect. lVhen but one vamp atatime is to be covered with cement on its skived edge, the tilting jaw H is rendered inoperative by withdrawing its pivot 0 and detaching it from the gravity-pipe E, or it can be held open by the lever N. The skived edge of the vamp is passed by hand over the reduced edge e of the cement-chamber F and covered with cement. When two vamps are to be cementcovered at a time, they are placed together with their skived edges outward and moved between the cement-chambers F J. The screw L and spring M afford the requisite pressure for bringing the cement-chambers together without interfering with the work. The lever N moving in unison with the tilting jaw does not impede the action of the jaw, it being for closing and holding the eemen t-chambers together while filling the upper cementchamber J through the lower one. A guide for regulating the insertion of the vamp between the jaws consists in a doubled wire it, held in place on the gravity-pipe E by setscrew 1',it-s long arm 20 extended into the cemerit-chamber F and upturned at I claim 1. In a cementing apparatus, the combination of a gravity-pipe, a vamp or cement seat on the gravity-pipe, and a tilting jaw pivoted on the gravity-pipe and provided with a ccment-chamber which receives cement through the gravity-pipe cement-chamber and the same gravity-pipe, for the purpose shown and described.

2. In a cementing apparatus, the combination of a gravity-pipe, a tilting jaw pivoted on the gravity-pipe under yielding pressure, and means for closing and holding the tilting jaw on the gravitypipe cement chamber while filling the tilting-jaw cement-chamber from the gravity-pipe cement-chamber, for the purpose shown and described.

3. In a cementing apparatus, the combination of a cement-chamber, a gravity-pipe, a tilting jaw, and an adjustable guide which regulates the extent of insertion of the vamp into the ccmenting-chamber, for the purpose shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

ALONZO B. MCCOY.
